In making these new roads Haussmann showed a constant concern for perspective and layout, creating the vast regulated thoroughfares that remain the main characteristic of the Second Empire works in Paris. The Boulevard Malesherbes, running north-west from La Madeleine, was itself broken up by the perspective created by the dome of St Augustin. Less felicitous, however, was the hemming in of the new Opera by Charles Garnier (completed only in 1875) by ten avenues.
